Explosive gas precautions

1. Working in the vicinity of batteries may be dangerous. Batteries can generate explosive gases during normal operation. Therefore, you must read this guide and follow the instructions exactly before installing or using your XW Inverter/Charger.

2. To reduce the risk of battery explosion, follow these instructions and those published by the battery manufacturer and the manufacturer of the equipment in which the battery is installed.

Precautions When Working With Batteries

1. Follow all instructions published by the battery manufacturer and the manufacturer of the equipment in which the battery is installed.

2. Make sure the area around the battery is well ventilated.3. Never smoke or allow a spark or flame near the engine or batteries.4. Use caution to reduce the risk of dropping a metal tool on the battery. It could

spark or short circuit the battery or other electrical parts and could cause an explosion.

5. Remove all metal items, like rings, bracelets, and watches when working with batteries. Batteries can produce a short circuit current high enough to weld metal to skin, causing a severe burn.

6. Have someone within range of your voice or close enough to come to your aid when you work near a battery.

7. Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.

8. Wear complete eye protection and clothing protection. Avoid touching your eyes while working near batteries.

9. If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters your eye, immediately flood it with running cold water for at least twenty minutes and get medical attention immediately.

1 Introduction

Chapter 1, “Introduction”, describes the operational features of the XW Series Inverter/Charger.

Topics in this chapter include:• “Basic Features” on page 1–2• “Basic Operation” on page 1–3

Introduction

Basic FeaturesCongratulations on your purchase of a XW Series Inverter/Charger from Xantrex Technology Inc. The XW Inverter/Charger is one of the finest inverter/chargers on the market today, incorporating state-of-the-art technology, high reliability, and convenient control features.Additional XW Inverter/Charger features include:• Building block power levels—units can be installed in parallel configuration

to produce up to 18 kilowatts• High efficiency true sine wave output• Split phase output on 120/240 60 Hz models to simplify system configuration

by eliminating the need for an autotransformer or stacking multiple inverters• Surge capacity to start difficult loads like well pumps, refrigerator or A/C

compressors• Power factor-corrected (PFC) input minimizes AC power required for

charging, effectively increasing AC pass-through capacity• High output, multi-stage charging to minimize charging time• Easy to configure and install systems at a competitive dollar-per-watt cost• Optional XW Automatic Generator Start allows operation with a wide range

of generators, supported through a dedicated generator input• Supports multi-mode grid-tie operation• Integrated transfer switch• Temperature-controlled, variable-speed internal cooling fan. The fan turns on

when the internal temperature reaches 45 °C and reaches maximum speed at 70 °C. The fan turns off when the internal temperature falls to 40 °C.

• Housing design promotes vertical air flow through the inverter. This natural “chimney effect” helps provide convection cooling at lower power levels, and reduces fan run time.

• Designed for reliability and field serviceability.System component

The XW Inverter/Charger uses Xanbus™, a network communications protocol developed by Xantrex, to communicate its settings and activity to other Xanbus-enabled devices. You can configure and monitor the XW Inverter/Charger and every Xanbus-enabled device in the system using an XW System Control Panel (part number 865-1050).

Basic Operation

Basic OperationThe XW Series Inverter/Charger is a modular “building block” sine-wave inverter/charger that can be used for both residential and commercial stand-alone, grid-backup, and grid-tie applications with battery energy storage. The XW Inverter/Charger is a self-contained DC to AC inverter, battery charger and integrated AC transfer switch. Up to three inverters can be installed together in a 120/240 V split phase configuration.

Multi-unit operation Inverting For multiple XW Inverter/Chargers, the master inverter/charger broadcasts pulses on the Xanbus network to synchronize and arbitrate operation between the other paralleled units. This coordination of multi-unit operation results in reduced tare loss and improved efficiency—other paralleled units stay in low-power mode until they are needed.For paralleled XW Inverter/Chargers, only one inverter/charger operates, and additional devices come on-line only when the load exceeds approximately 60 per cent of the rated output of the master inverter/charger. In a three-unit system, additional slave units come on sequentially if the load on the master does not drop below 60 per cent about 3 to 5 seconds after a slave unit turns on to assist the master. When the load drops below 20 per cent of the master’s rated output, the slave units turn off in reverse order; that is, the last slave unit to turn on will be first to turn off.The current sharing imbalance for a single inverter/charger does not exceed 10 per cent of the rated maximum nominal output power. All non-utilized inverter/chargers are off-line when no load is present.Parallel charging When multiple XW Inverter/Chargers are charging in a system, they synchronize charging stages to ensure efficient charging of the battery bank. All units transition from bulk to absorption when a single unit does. In absorption, all units must complete the absorption stage before transitioning to the next stage. Note that units do not load share when charging. Each unit charges batteries based on the Max Charge Rate setting and active internal (temperature-based) deratings.If equalize is enabled on one or more devices capable of equalization charging (such as XW Inverter/Chargers or XW Series Solar Charge Controllers), only those devices initiate and perform a equalize cycle after absorption. Other devices will float (if three-stage charging is selected) or transition to AC pass-through (if two-stage charging is selected).When one or more XW Series Solar Charge Controllers are installed and operating in the system, the XW Inverter/Chargers synchronize charging stage (bulk, absorption, or float) with the charge controllers. In a similar fashion to the XW Inverter/Charger charge behavior, charge controllers also harmonize charging among themselves.AC Transfer XW Inverter/Chargers monitor each other using a peer-to-peer monitoring technique to determine the quality of AC input. If AC input is deemed bad by any of the paralleled units, no transfer to AC occurs and the units may

Introduction

continually flash the AC LED on their respective information panels. If the system was in pass-through and AC fails on any unit, all units transfer to invert simultaneously.Faults When an XW Inverter/Charger in a multi-unit system has a fault, only the affected device shuts down, except in the following cases:• When a master unit has an invert mode fault that causes it to stop inverting, a

system wide fault occurs. Invert mode faults on a slave unit shut down only the affected slave unit.

• Battery-related faults such as battery over-temperature or over-voltage.Other modes of operation XW inverter/chargers operate independently when in grid support mode (including sell mode), load shave, generator support and charger block modes. This allows units to be configured to perform a multiple of functions independently and allowing greater flexibility in operating the system.

Auxiliary output Each XW Inverter/Charger has one programmable auxiliary output that is able to run a small 12 V fan or operate an external relay to perform other functions, such as to remotely start a generator (if the Xanbus-enabled XW-AGS is not used), to disconnect external non-critical loads, or to turn on a diversion load for battery voltage regulation.

Transfer relay The built-in transfer relay is rated for 60 amps. When an external AC source is detected on either of its two AC inputs, the switch transfers loads from the XW Inverter/Charger to the external power source, and then activates the battery charger to re-charge the battery bank.

AC1 and AC2 relay The XW Inverter/Charger design does not allow the AC1 and AC2 inputs to feed into each other. The relays controlling AC1 and AC2 input can never close simultaneously. This design prevents generator input from feeding out to the utility grid.

Surge Performance

Unlike many other inverters, the XW Inverter/Charger prevents voltage from sagging dramatically during surge conditions. The XW Inverter/Charger handles surges of over twice the inverter’s rated output with only a minimal drop in output voltage.

Basic Operation

Islanding Protection

Islanding protection is an essential safety feature that ensures no person working on the utility grid is harmed by a distributed energy source, such an XW Inverter/Charger. Islanding protection also prevents loads connected to the inverter from being damaged by fluctuating utility grid input. Default software settings are programmed into each XW Inverter/Charger at the factory to ensure it does not “island” according to applicable safety regulations (such as IEEE 1547 and UL 1741).As well, the XW Inverter/Charger uses a proprietary positive feedback controller that has minimal effect on total harmonic distortion, and is guaranteed to detect islanding conditions for all power levels, as governed by IEEE and UL standards.In some instances it may be desirable from both a utility and customer point of view to adjust default anti-islanding settings. For example, the XW Inverter/Charger may experience “nuisance trips” if the grid is weak and the voltage falls outside the allowable range specified in the regulations. It may be difficult for a utility to upgrade the grid to eliminate this problem. With permission from the utility, the factory settings may be changed to allow the XW Inverter/Charger to operate over a wider grid voltage range.These settings should only be changed by qualified service personnel, using a special software application provided by Xantrex. Changing any values may compromise compliance with safety regulations. Do not do so without first consulting with the utility and agreeing on acceptable settings.While selling power, the XW Inverter/Charger continuously monitors utility grid voltage and frequency. If the grid voltage and frequency move beyond the XW Inverter/Charger default ranges1—during a power surge or outage, for example—the XW Inverter/Charger stops selling power to AC1 and disconnects from the utility grid for five minutes (Five minutes is the minimum reconnect time, and is not adjustable.) If the utility grid voltage and frequency have returned to their nominal values when the reconnect time has expired, the XW Inverter/Charger begins selling power again.The Fault light on the XW Inverter/Charger information panel indicates that a utility fault has occurred. No fault code appears on the three-character display because the fault is with the utility grid, not the XW Inverter/Charger.The XW System Control Panel indicates a utility fault with the Fault light and a fault message on its screen (faults F23 to F40 are utility faults—see Table 4-5 on page 4–18). The fault cannot be manually cleared. Utility faults clear automatically when the utility grid voltage and frequency return to their nominal values.

Monitoring Operation

Monitoring Operation with the Inverter Information PanelThe Inverter Information Panel displays basic information that enables you to monitor a single XW Inverter/Charger. The Inverter Information Panel also allows you to turn the XW Inverter/Charger on and off and start battery equalization. LEDs on the Information Panel indicate AC input status, inverter status, battery condition, and charging and equalization status. The LEDs and three-character display screen also alert you to XW Inverter/Charger warning and fault conditions.

Monitoring AC Input Status

Grid (AC1) The green Grid (AC1) LED indicates the presence and status of AC source connected to the AC1 input. In most installations, AC1 input is from the utility grid. However, any AC source can be connected to the AC1 input.

Gen (AC2) The green Gen (AC2) LED indicates the presence and status of a generator or other auxiliary AC source on the AC2 input.

Monitoring Operation with the Inverter Information Panel

When one AC input LED is on and the other AC input LED is flashing, AC input is present on both AC1 and AC2. However, the XW Inverter/Charger can qualify and receive AC input from only one source at a time. The qualified source is represented by the LED that is on. When two sources of AC input are present, the XW Inverter/Charger uses the source selected under AC Priority on the System Control Panel AC Settings menu. The AC sources connected to AC1 and AC2 can be the utility grid and a generator, or two generators.

Monitoring Inverter Status

The green kW LED indicates the XW Inverter/Charger is inverting DC input to AC output. When this LED is on or flashing, the display screen shows inverter output power in kilowatts.

Monitoring Charger Status

The green A LED indicates the XW Inverter/Charger is charging the battery bank. When this LED is on, the display screen shows battery charging current in amps.

Equalizing Batteries

Button Pressing the Equalize button (indicated by the symbol) for five seconds turns battery equalization on and off. After this button is pressed, the XW Inverter/Charger begins the equalization charge after the next charge cycle is complete. Equalization functions only if AC is present and qualified and the charger is enabled. Otherwise the inverter/charger generates a “cannot equalize” fault (W96).

For more information, see “Equalize Charging the Batteries” on page 3–13LED The yellow Equalize LED indicates that the XW Inverter/Charger is equalizing

batteries.

Symbol LED On LED Flashing

The XW Inverter/Charger has a fault and has stopped charging or inverting. The LED also turns on steadily if the unit has both a fault and a warning.

The XW Inverter/Charger has a warning. Warnings may escalate to a fault if the warning condition does not go away.

CAUTION: Battery damageEqualization may damage your battery. Consult your battery supplier for details on equalize charging for the battery type in your system.

Important: In a system where more than one device is capable of equalizing batteries (such as a system including multiple XW Inverter/Chargers and Solar Charge Controllers), there is no system-wide equalization command for all devices. To equalize with multiple devices, each would have to be enabled individually. Alternatively, equalization can be performed using only one device. During the equalization process, one device applies the equalization charge while the other devices continue to operate in synchronized charge mode, typically in float (three-stage charging) or no-float (two-stage charging).

Symbol LED On LED Flashing

Monitoring Operation with the Inverter Information Panel

Turning the XW Inverter/Charger On and Off

On/Off control When the XW Inverter/Charger is operating, pressing and holding the On/Off button () for five seconds turns the unit off. Pressing the On/Off button momentarily returns the unit to its previous operating state.When the XW Inverter/Charger is being turned off, the other Inverter Information Panel buttons stop working. The shutdown process cannot be cancelled. The XW Inverter/Charger can only be turned back on once the display is blank.

Standby mode In Standby mode, the XW Inverter/Charger stops charging, inverting, and passing through AC input. However, the unit remains powered up and present on the Xanbus network.To put the XW Inverter/Charger into Standby mode, press and hold the On/Off button and the Equalize button simultaneously for about five seconds. The display shows “Stb.” To return the XW Inverter/Charger to operating mode, press the On/Off button momentarily.Pressing the On/Off button momentarily while the XW Inverter/Charger is operating clears active faults and warnings.

Single-unit installations

In a single-unit installation, when the XW Inverter/Charger is turned off using the On/Off button, Xanbus network power is lost. When Xanbus network power is lost, network-connected accessories such as the Automatic Generator Start (XW-AGS) and XW System Control Panel lose power and stop operating. XW Charge Controllers continue to operate and communicate between each other if Xanbus network power is removed.

Multiple-unit installations

If the On/Off power button is pressed and held on a master XW Inverter/Charger (see “Inverter Mode” on the “Multi-Unit Config Menu” on page 3–23) and an XW-AGS is installed in the system, the unit stops inverting/charging immediately and turns off completely in 120 seconds. During this time, the display shows “OFF.” This interval allows the XW-AGS to stop the generator after a “cool down” period. During the 120-second shutdown time all network communication is blocked and the unit sends a shutdown command to all other devices in the system. As well, the Inverter Information Panel buttons stop working and the shutdown process cannot be cancelled. The XW Inverter/Charger can only be turned back on once the display is blank.In a multiple-unit installation, when a Slave XW Inverter/Charger is turned off, other XW Inverter/Chargers continue to supply Xanbus network power and the XW-AGS and XW System Control Panel continue operating.

975-0240-01-01 2–5


Monitoring Battery Level

The row of five LEDs indicates the approximate capacity of the batteries connected to the system. The capacity reading is based on current-compensated battery voltage.There are four battery states: empty, low, medium, and full. When the battery capacity is empty, no LEDs are lit. The battery is considered empty when its depth of discharge exceeds approximately 50%. When the battery capacity is low, the leftmost two LEDs are lit. When the battery is at medium capacity, the leftmost four LEDs are lit. When the battery capacity is full, all five LEDs are lit.

Reading the Display Screen

The three-character display screen shows the following information about the operational state of the XW Inverter/Charger:• Output power in kilowatts when the XW Inverter/Charger is inverting. and the

kW LED is lit.• Battery charger current when the XW Inverter/Charger is charging and the

A LED is lit.• “Stb” when the XW Inverter/Charger is in Standby mode.• “Sch” when the XW Inverter/Charger is in Search mode. See “Using Search

Mode” on page 3–8.• “OFF” when the on/off button is pressed and held for five seconds. “OFF” is

displayed briefly before the unit turns off.• “– – –” briefly when the XW Inverter/Charger is in transition between modes,

for example, qualifying AC input. The display also shows “– – –” when the XW Inverter/Charger has been manually disconnected from renewable energy power sources and is operating in bypass mode.

• “En” momentarily when the inverter is enabled.• “dIS” momentarily when the inverter is disabled.

Table 2-1 XW Inverter/Charger Home Screen States

XW Inverter/Charger Status Displayed When...

Invert The XW Inverter/Charger is supplying power to loads by inverting power from the batteries. AC input from the utility or generator is absent or out of nominal range.

Qualifying AC The XW Inverter/Charger is determining if AC input is within a usable voltage and frequency range. “Qualifying AC” is also displayed when the XW Inverter/Charger is awaiting application of AC power or a command to enable invert mode.

Charging The XW Inverter/Charger is charging the batteries from qualified AC input from the utility grid or a generator. The charge state is in transition to either Bulk, Absorption, Float or Equalize. AC input is also passed through to the load while charging.

Bulk The XW Inverter/Charger is bulk charging the batteries from qualified AC input from the utility grid or a generator. AC input is also passed through to the load while bulk charging.

Absorption The XW Inverter/Charger is absorption charging the batteries from qualified AC input from the utility grid or a generator. AC input is also passed through to the load while absorption charging.

ABS Finish The XW Inverter/Charger has completed the absorption stage and is waiting for other chargers in the system to complete absorption. This status can occur only when there is another device (an inverter/charger or charge controller) also charging the battery.

Float The XW Inverter/Charger is float charging the batteries from qualified AC input from the utility grid or a generator. The XW Inverter/Charger is set for three-stage charging. AC input is also passed through to the load while float charging.

CHG Finish The XW Inverter/Charger has completed charging or the charge cycle has been interrupted and is transitioning to the next state. This stage last about one minute, while the battery is allowed to settle. The delay keeps the inverter/charger from unnecessarily transitioning to Grid Support (if enabled) after a charge cycle.

2–12 975-0240-01-01


Fault The XW Inverter/Charger has an active fault. The Fault/Warning light on the System Control Panel is on.

Gen Support There is AC input from the generator, and the XW Inverter/Charger is supporting the generator by supplying additional power to the critical loads.The XW Inverter/Charger supports the generator (or other power source connected to the AC2 input) when the AC load current drawn from AC2 exceeds 80 per cent of the AC2 breaker setting or GenSup Amps setting for 1 to 2 seconds.The XW Inverter/Charger uses stored DC capacity to load share with the generator until the total AC load current (generator plus inverter output) drops by 2 amps plus 10 per cent of the GenSup Amps setting for 6 seconds.For example if GenSup Amps is set to 10 amps, the inverter starts to support when the load exceeds 10 amps for 2 seconds and stops when it drops more than 3 amps below the GenSup Amps setting, or 7 amps (2 amps plus 10 per cent of 10 amps = 3 amps).The system can enter this state if the battery voltage is above the Low Batt Cut Out setting and Gen Support is enabled. See “Generator Support Settings” on page 3–21.

Grid Support There is AC input from the utility and the XW Inverter/Charger is supporting the utility grid by supplying additional power to the critical loads.The XW Inverter/Charger supports the utility grid by limiting the power drawn from the utility to less than 10 per cent of the load demand. This mode is desirable for using excess energy from auxiliary DC sources like PV, while still maintaining a charged battery bank. No power is sold to the utility in this mode.The XW Inverter/Charger uses stored DC capacity to support the grid until the total AC load current (grid plus inverter output) drops by 2 amps plus 10 per cent of the Load Shave Amps setting for 6 seconds.The XW Inverter/Charger enters this state only when the Grid Support is set to “On” and battery voltage is above the Grid Supp Volts setting. See “Grid Support Settings” on page 3–17.

Load Shaving There is AC input from the utility, and the XW Inverter/Charger is supporting the utility grid when the current required to power the loads rises above the Load Shave Amps setting between the Load Shave Start and Load Shave Stop times set on the Grid Support menu.Many utilities impose a surcharge on their customers based on the peak load used by a facility. When load shaving, the XW Inverter/Charger uses stored DC capacity to reduce the peak load on the utility grid and keep current draw from the grid equal to or under the Load Shave Amps setting. The XW Inverter/Charger enters this state only when Grid Support is enabled, the Load Shave time window is valid and the load draw exceeds the Load Shave Amps setting. See “Grid Support Settings” on page 3–17.

Search Search Mode is enabled and the XW Inverter/Charger is standing by, waiting to begin inverting. See “Using Search Mode” on page 3–8.

SellToGrid The XW Inverter/Charger is grid tied (grid voltage and frequency are within the limits specified by UL1741) and selling power to the utility grid. Both Grid Support and Sell must be enabled in order to sell power back to the utility. See Table 3-1 on page 3–3 and “Grid Support Settings” on page 3–17.

Inverter Settings MenuThe Inverter Settings Menu contains settings that control when the XW Inverter/Charger turns on and off when it is inverting.

For default settings, see “Inverter Menu” on page B–3.

Using the Low Battery Cut Out and LBCO Delay Settings

The Low Batt Cut Out setting is the lowest voltage level acceptable for battery use by the inverter. When the batteries discharge to the Low Batt Cut Out setting, and are held at or below this level for the LBCO Delay time, the inverter output shuts down and transfers any available AC source (generator or grid) to the charger to

Table 3-2 Inverter Settings menu

Item Description

Low Batt Cut Out

This setting controls when the inverter turns off due to a low battery voltage condition. The inverter will turn off only after this level has been reached for the period of time set by the LCBO Delay. This setting is not temperature compensated.

LBCO Delay

LBCO Delay controls how long the inverter is allowed to operate at or below the Low Battery Cut Out level before turning off due to a low battery voltage condition. The inverter will turn off only after the Low Batt Cut Out level has been reached for this uninterrupted period of time.Once the inverter has shut off, the battery voltage must rise 4 volts above the Low Batt Cut Out setting for inverter operation to resume.

High Batt Cut Out

High Batt Cut Out sets the maximum battery voltage at which the inverter will operate. If the battery voltage exceeds this limit for more than 1 minute, the inverter displays a fault message (F49) and shuts down. The inverter will not support AC loads when in this condition. If a qualified AC source is present, the unit passes AC through to the loads. The inverter automatically restarts when the voltage drops to 3 volts (24-volt system) or 6 volts (48-volt system) below the High Batt Cut Out setting. If battery voltage continues to rise after shutdown, an external charger may still be charging the batteries. The XW Inverter/Charger cannot control how external chargers operate.

Search Watts

Search Watts sets the inverter’s search sensitivity when Search mode is enabled. When a load larger than this setting is present, the inverter turns on. Enabling Search mode from the Setup Menu (see page 3–2) can minimize power draw from the battery during periods of low demand from loads. Also see “Using Search Mode” on page 3–8.

Search Delay

Search Delay sets the time between search pulses. When searching for loads, the XW Inverter/Charger sends out search pulses to determine if a load is present. If the XW Inverter/Charger finds a load above the Search Watts setting, the inverter comes on. XW Inverter/Charger power draw while in Search mode decreases when Search Delay is increased, but the inverter’s response time to active loads is reduced.

975-0240-01-01 3–7

Configuration

bring the battery level back above the Low Batt Cut Out setting. After shutdown, the inverter does not support any AC loads, and AC loads must be powered by either a generator or grid power.If using an automatic generator starting system, it is recommended to set the AGS voltage trigger setting higher than the XW Inverter/Charger Low Batt Cut Out voltage. Otherwise, inverter output turns off and then back on when the generator auto-starts.If using an automatic generator starting system with the start trigger set to the same voltage as the LBCO voltage, do not set the LBCO Delay for less than the amount of time it takes the generator to start and connect. Otherwise, inverter output turns off and then back on when the generator auto-starts.

Using Search Mode

While idling in Search mode, the inverter sends out an electrical search pulse that travels through the AC wiring “looking” for connected loads. The frequency of the search pulse is set using the Search Delay setting.After a load larger than the Search Watts setting is detected, the inverter turns on.

Why use Search mode?

Search mode allows you to selectively power only items that draw more than a certain amount of power, which can result in power savings.The XW Inverter/Charger has a no-load power draw of about 28 watts. Enabling Search mode reduces this power draw to less than 8 watts.

When to set up Search mode

The Search mode feature on the inverter is only valuable if the inverter can spend a fair amount of time “sleeping” each day. Therefore, if Search mode is to be utilized it must be adjusted properly. The initial adjustment should be made so that the inverter comes on only when needed.Certain types of loads can cause Search mode not to work as expected. These types of loads are described on page 4–3 of the Troubleshooting chapter. If these kinds of loads are in the system, follow the suggestions given to eliminate the problem. Some televisions with instant-on circuits have a menu or control to disable it. If clocks are the problem load, consider using battery-powered units.If the problem loads cannot be eliminated, there are two work-around solutions:1. Disable Search Mode from the main XW Inverter/Charger Setup menu,

causing the inverter to always remain at full output voltage.2. Use a search-friendly “companion load” whose only purpose is to be switched

on to “wake up” the inverter to power the load that is unable to bring the inverter out of Search mode.

Important: Search mode does not function in installations with multiple XW Inverter/Chargers. The combined current draw of multiple inverter/chargers falsely brings the units out of Search mode. Search Mode should be disabled on the Setup menu of each XW Inverter/Charger.

Notes:• Search mode, by function, cannot work with clocks and timers or devices that need

power 24 hours a day. Examples of devices with timers include video recorders, coffee makers with brew timers, refrigerators, and freezers with defrost timers. Examples of devices that need power 24 hours a day include telephone answering machines, alarm systems, motion detection lights, and some thermostats.

• When the inverter is searching the output for loads, lights that have a wattage lower than this setting may flash momentarily.

Battery Charger Functions

When AC power is available, the XW Inverter/Charger can operate as a battery charger. Different battery types and chemistries require different charging voltage levels. Not charging batteries at the required levels can shorten battery life or possibly damage them. The XW Inverter/Charger is configured at the factory to work with the battery types recommended for inverter applications. If the default settings do not work for your specific installation, you can adjust the charge stage settings (as recommended by the battery manufacturer) on the Custom Battery Settings menu (see page 3–15). It will be necessary to select the voltage levels required and to set the voltage limits for the various stages of charging.

Multi-Stage Charging Process

The charging cycle uses a multi-stage charging process to maintain the batteries. Whenever AC power that is within the range of the inverter’s settings is present at the inverter’s input, it passes power through to the connected load and begins charging the batteries.

Bulk Stage Bulk charge is the first stage in the charging process and provides the batteries with a controlled, constant current. Once the battery voltage rises to the bulk voltage threshold, the charger switches to the Absorption stage.

Note: This information is provided for guidance only. Variations in battery chemistry and site-specific environmental considerations mean that you should consult your system designer or battery manufacturer for specific recommendations for appropriate battery voltage and current settings.

Configuration

Absorption Stage Absorption charge is the second stage of battery charging and provides the batteries a controlled, constant voltage. During this stage, the current supplied to the batteries slowly decreases. When this current falls below 2% of the battery capacity, or when the configurable Absorb Time expires, the charger switches to the Float or NoFloat stage, depending on the selected charge cycle.

Float Stage Float charge maintains a trickle charge on the batteries whenever AC is present on the inverter’s input. Float charging reduces battery gassing, minimizes watering requirements (for flooded batteries), and ensures the batteries are in a constant state of readiness. When three-stage charging is selected, the charger will automatically switch to the float stage after the batteries have received a bulk and absorption charge (see Figure 3-4 on page 3–11). The batteries will be maintained at the default float voltage level for the selected battery type or the voltage selected under Float Voltage on the Custom Battery Settings menu.

2-Stage 2-Stage (or No Float) mode differs from an ordinary three-stage charge mode in that it does not continuously maintain the battery at float voltage. Instead, the XW Inverter/Charger begins charging the battery in bulk mode whenever the battery voltage drops below the recharge level. While the battery voltage is above the recharge level the inverter’s AC transfer switch continues to pass power through from the utility grid to the loads, but does not actively charge the batteries. 2-Stage mode increases efficiency of utility connected systems by reducing the amount of power consumed by the inverter and batteries compared to when the battery is continuously maintained at Float voltage. This feature can extend the life of most batteries.To allow Grid Support and Sell Mode to function after battery charging has completed, it is recommended to set the Charge Cycle to 2-Stage.

Note: If there are DC loads on the batteries, the charger’s current may never decrease to a level to initiate the next stage of charging. In this case, the charger would stay in absorption until the Absorb Time setting is reached.To ensure the charger does not remain in absorption for too long, adjust Absorb Time on the Charger Settings menu. The timer begins at the start of the absorption stage and terminates absorption charging if the charge current does not decrease to below 2% of the battery capacity before the Absorb Time setting expires. The Absorb Time setting may be increased if the charge cycle continually runs the full Absorb Time in the absence of DC loads. This is an indication of too large a battery bank for the selected Absorb Time setting.

Note: The battery voltage can increase above the float voltage when using an external charging device such as PV arrays, wind turbines, and micro-hydro generators. Be sure to include appropriate charge management equipment with all external DC sources.

Note: If the AC input fails or drops below the lower Vac limit (as set in “AC Settings”), the complete multi-stage charge cycle (Bulk, Absorption, Float/No Float) restarts once the source AC returns to an in-tolerance condition. If the batteries are already nearly full, the charge cycle will take little time to complete.

3–12 975-0240-01-01


Equalize Charging the Batteries

Many battery manufacturers recommend periodic equalize charging to level out the voltage between individual cells, improving battery performance and lifespan.Over time, the battery’s electrolyte can become “stratified,” causing inactive areas in the plate material. If this condition is allowed to continue for extended periods, the battery plates can “sulfate” and become unusable. Equalizing the batteries is a controlled overcharging method that mixes up the electrolyte and reactivates the unused areas of the plate material, restoring batteries to a full state of charge.Consult the battery manufacturer’s recommendation for equalize charging settings.To start equalizing the batteries:u On the XW Setup menu, highlight Equalize and select Enable.

OrPress the equalize button on the Inverter Information Panel for five seconds.

WARNING: Explosion hazardOnly flooded or vented batteries should be equalize charged. Hydrogen and oxygen gases are produced when batteries are equalize charged. Provide adequate ventilation and remove all sources of ignition to prevent explosion.

Important: In a system where more than one device is capable of equalizing batteries (such as a system including multiple XW Inverter/Chargers and Solar Charge Controllers), there is no system-wide equalization command for all devices. To equalize with multiple devices, each would have to be enabled individually. Alternatively, equalization can be performed using only one device. During the equalization process, one device applies the equalization charge while the other devices continue to operate in synchronized charge mode, typically in float (three-stage charging) or no-float (two-stage charging).

975-0240-01-01 3–13

Configuration

Using Charger Block

The Charger Block feature halts charging on AC1 (Grid) for a period of time each day. This period of time is defined by the Chg Block Start and Chg Block Stop settings. In areas where the utility charges variable rates for electricity, it is preferable to use utility power for charging only during non-peak hours. Charger Block can prevent utility power from being used for battery charging during peak billing periods.During the time period set between Chg Block Start and Chg Block Stop, AC1 (Grid) input continues to be passed through to the loads. Inverter operation remains unaffected during the charger block period.During the Charger Block period, no charging on AC1 occurs even if the batteries discharge below ReCharge Volts setting. However, a generator connected to AC2 (in the absence of utility/AC1 power) or an XW Solar Charge Controller may charge batteries during the Charger Block period. AC priority must be set to AC2 to charge batteries with a generator connected to AC2 during the Charger Block period.If the charger is operating (that is, in Float, Absorption, Bulk or Equalize stage) at the Chg Block Start time, charging on AC1 stops immediately and the charger enters an idle state identical to No Float (see “2-Stage” on page 3–12). When the Charger Block period is over, the charger does not resume the charge stage that Chg Block Start interrupted. Instead, if the batteries are above the ReCharge Volts setting, the charger remains idle.If the batteries have fallen to the ReCharge Volts setting during the Charger Block period, the XW Inverter/Charger begins a new charge cycle with the Bulk stage after the Charger Block period has expired (at the Chg Block Stop time).For example, Charger Block is set to start at 5:00 PM and end at 8:00 PM. If the XW Inverter/Charger is charging from AC1, charging stops at 5:00. When Charger Block ends at 8:00, the XW Inverter/Charger does not automatically resume charging. The unit first measures the battery voltage. If the voltage is below the ReCharge Volts setting, then the XW Inverter/Charger starts a new charge cycle from Bulk. If the battery voltage is above the ReCharge Volts setting, the XW Inverter/Charger remains idle and continues passing through AC to the loads. The XW Inverter/Charger also keeps measuring the battery voltage as before to determine whether to start a new charge cycle.

Configuration

AC SettingsThe AC Settings menu configures the voltage and frequency limits for AC line 1 (grid) and AC line 2 (generator). These are the limits at which the XW Inverter/Charger considers input voltage qualified—that is, suitable for charging batteries or powering loads. If the input voltage is not qualified according to these settings, the XW Inverter/Charger transfers from using AC input to inverting.

For default settings, see “AC Menu” on page B–4.

Table 3-5 AC Settings menu

Item Description

AC Priority Sets the priority for the AC source (AC1 or AC2) for qualification and transfer. For example, this setting allows the XW Inverter/Charger to use a renewable energy source (such as an AC hydro generator) connected to AC2 on a first-priority basis and use utility power only when renewable energy is insufficient or unavailable to power loads.

In systems that use both utility grid (AC1) and generator (AC2) input, AC Priority is recommended to be set to AC2. Assuming the generator is intended for occasional use only, the XW Inverter/Charger will use utility power until the generator is started.

AC1 Breaker Sets the AC1 (Grid) breaker size, based on the size of the breaker installed on AC1. The installed breaker size must not exceed the capacity of the upstream distribution panel. The XW Inverter/Charger limits the maximum input current to this setting by derating its charging current. If the connected loads exceed the AC1 breaker setting, the AC breaker trips (causing fault F63, F64, or F65). The breaker may not trip if Grid Support is enabled and battery voltage is above the Grid Support Volts setting, or if Peak Load Shave is enabled and the Load Shave Time window is active.

AC1 Lo Volt Minimum acceptable input voltage level from the utility grid.AC1 Hi Volt Maximum acceptable input voltage level from the utility grid.AC1 Lo Freq Minimum acceptable utility grid input frequency.AC1 Hi Freq Maximum acceptable utility grid input frequency.AC2 Breaker Sets the AC2 (Gen) breaker size, based on the size of the installed AC

breaker. The breaker size must not exceed the capacity of the generator. The XW Inverter/Charger limits the maximum input current to this setting by derating its charging current. If the connected loads exceed the AC2 breaker setting, the AC breaker trips (causing fault F63, F64, or F65). The breaker may not trip if Grid Support is enabled and battery voltage is above the Grid Support Volts setting, or if Peak Load Shave is enabled and the Load Shave Time window is active.

Grid Support Settings

Grid Support SettingsThe Grid Support Settings menu contains configuration options for grid-tie operation. To enable all these settings, Grid Support must be enabled in the Setup menu (see “XW Inverter/Charger Setup Menu” on page 3–2).

Important: To allow Grid Support to function after battery charging has completed, it is recommended to set the Charge Cycle to 2-Stage. After completing the absorption charger stage the XW Inverter/Charger checks whether battery voltage is above the Grid Supp Volts setting. If battery voltage is above the Grid Supp Volts setting, the XW Inverter/Charger uses available DC power to support the loads. See “Charger Settings Menu” on page 3–10.

Turning the charger off also enables Grid Support functionality.

If the Charge Cycle is set to 3-Stage, the Grid Supp Volts setting must be higher than the float voltage setting for your battery type for Grid Support settings to function (see “Custom Battery Menu” on page B–4 for default Float voltage settings).Important: Upon startup, the XW Inverter/Charger does not enable Grid Support functions for five minutes. During this five-minute period the XW Inverter/Charger determines whether the utility grid voltage and frequency are stable and within nominal range. For more information, see “Islanding Protection” on page 1–5.

Table 3-6 Grid Support Settings menu

Item Description

Grid Supp Volts Sets the level to which the batteries will be discharged when the inverter is selling power to the grid or supporting the power grid by providing additional power to the loads. This setting is not adjusted for the battery temperature if the temperature sensor is installed.

Sell Turns Sell mode on and off. When Sell is enabled, the XW Inverter/Charger AC output is divided between powering loads and delivering power to the utility grid. Sell mode requires the battery voltage to be above the Grid Supp Volts.

Max Sell Amps Sets the maximum AC amps allowed to be delivered to the utility grid from a solar array and/or the batteries during grid-tie operation. This setting is only used if Sell mode is enabled.The Max Sell Amps must be less than 80 per cent of the selected AC1 breaker setting. If set higher, the breaker setting will override the Max Sell Amps setting to avoid tripping the breaker.

Load Shave Enables or disables the Load Shave feature. Load Shave allows the XW Inverter/Charger to support the grid in powering local loads during a defined window of time (set using Load Shave Start and Load Shave Stop). When in this mode, the XW Inverter/Charger operates until the batteries discharge to the LBCO threshold, after which the unit reverts to AC pass-through. The charger is automatically blocked during the Load Shave time window.

Energy Management

The XW Inverter/Charger can be programmed to control how and when to use utility power. Advanced features allow management of peak loads and time-of-use billing.

Charger Block

See “Using Charger Block” on page 3–14.

Grid Support

The Grid Support feature allows the XW Inverter/Charger to support local loads by converting excess capacity from external DC sources connected to its battery bank. Examples of external DC sources are charge controllers, micro-hydro, and wind turbines.For Grid Support to function, Grid Support must be enabled on the Setup menu and the battery voltage must be above the Grid Supp Volts setting.There are two modes of operation within Grid Support.Grid Support enabled, Sell disabled In this mode, available excess DC power is converted and used to power local loads. No power is exported to the utility. If the local load demand exceeds the available power from the external DC sources, power is then drawn from the utility to support the load. However, if the local load demand is less than the power available from external DC sources, the net excess power from the external DC sources is not converted and hence not used.

Load Shave Amps Sets the maximum amount of current that can be drawn from the AC1 (grid) input by the loads and battery charger combined. This setting determines the amperage level at which the inverter starts drawing power from the batteries to add to the utility power to meet the demand of the loads.Typically, this value is set to the size of the AC circuit breakers feeding the inverter’s AC input.

Load Shave Start Sets the time of day that the Load Shave feature operates. This feature is suited for regions where local utilities impose peak usage surcharges. The inverter provides load shaving power as long as battery voltage is above the Low Batt Cut Out setting.

Load Shave Stop Sets the time of day that the Load Shave feature stops operating. If Load Shave is enabled and Load Shave Start and Load Shave Stop are set to the same time, the XW Inverter/Charger load shaves continuously.

Table 3-6 Grid Support Settings menu

Item Description

3–18 975-0240-01-01

Grid Support Settings

Grid support enabled, Sell enabled In this mode all available excess DC power is first used to power local loads, and any excess is exported to the utility grid.

Peak Load Shaving

Many utilities impose a surcharge on their customers based on the peak load used by a facility. To reduce utility peak demand charges, the inverter can be configured (using the Load Shave Amps setting) to limit the maximum draw the AC loads place on the utility. The inverter can be programmed to provide power above a specified level, eliminating the surcharge. When the utility current draw reaches the maximum level, the inverter assists by providing battery powered AC to the loads.For Peak Load Shaving to be effective, all loads must be connected to the inverter. For large loads, multiple (or stacked) inverters may be required.To further ensure the batteries are able to supplement the power requirements of the connected load, an additional source of power (solar, wind or hydroelectric) is recommended.Peak Load Shaving can also be used in addition to the time-of-use metering.

Time-of-Use Metering

Utilities use time-of-use metering to determine utility charges during peak usage hours and to impose a surcharge. The XW Inverter/Charger can be configured (using the Load Shave Start, Load Shave Stop and Charger Block settings) to overcome these peak charges by using utility power to charge the battery bank during the inexpensive energy hours and consuming the battery energy during expensive energy hours.For example, if Charger Block is set between 9:00 AM and 10:00 PM and Load Shave is set between 6:00 PM and 9:00 PM, charging on AC1 stops at 9:00 AM and continues to pass utility AC through to the loads. If charging is required during the charger block period, and AC Priority is set to AC2, the XW Inverter/Charger can use any AC source connected to AC2. Loads will transfer to the AC source on AC2 as well. The inverter connects to the utility grid at 6:00 PM and supports loads using the batteries. The inverter continues to run until 9:00 PM. The XW Inverter/Charger then stops supporting the utility grid and passes utility AC through to the loads. At 10:00 PM utility AC begins maintaining the batteries based on the battery charger settings.The above example allows an external renewable energy source to be utilized as a primary charging source during a desired time window. The charger (using utility AC connected to AC1) can then be used to supplement the battery charging when the rates utility rates are low.

Note: Running and Start-up (Peak) currents are limited to the maximum current limits of the inverter.

975-0240-01-01 3–19

Configuration

When using the system for time-of-use metering, the system should be designed with a battery capacity large enough to support loads during the entire peak rate period without reaching the Low Battery Cut Out setting.To further ensure the batteries are able to support the loads, an additional source of power (solar, wind or hydroelectric) is recommended. Depending upon the capacity of the system, certain heavy loads should only be run during non-peak periods.

Note: In the event the batteries reach their Low Battery Cut Out voltage, the inverter will automatically reconnect to the utility grid to maintain the connected load.

3–20 975-0240-01-01

Generator Support Settings

Generator Support SettingsGenerator support allows power to be automatically drawn from the batteries to assist an AC generator to support heavy loads (loads that exceed the available current from the generator).Generators have a limited output current and it is possible to reach this limit when operating heavy loads. The XW Inverter/Charger is designed to assist the generator when heavy current demands load down the generator by supplying additional power from the batteries.In addition, the battery charger can back off its charging current to the batteries so the combined load of the charger and load support does not exceed the capacity of the generator or trip its output breakers or fuses.

For default settings, see “Gen Support Menu” on page B–5.

Auxiliary Output SettingsThe Aux menu allows you to enable and configure the auxiliary output. The auxiliary output provides 12 Vdc at 250 mA to power a relay, indicator light or alarm.

Note: Running and Start-up (Peak) currents are limited to the maximum current limits of the inverter.

Trigger Source Descriptions

Low Batt Voltage Activates the Auxiliary Output when the battery voltage falls below the Low Batt Voltage setting for the trigger delay time. The Auxiliary Output turns off when the battery voltage rises above the Clear setting for the Clear Delay time. Use this setting if you want the auxiliary output to control a relay to disconnect loads from a battery that is nearly discharged, or to activate a low-battery-voltage alarm such as a buzzer or light.High Batt Voltage Activates the Auxiliary Output when the battery voltage rises above the Hi Batt Voltage setting for the trigger delay time. The Auxiliary Output turns off when the battery voltage falls below the Clear setting for the Clear Delay time. This setting is useful for:• Installations that have another external charging source such as a wind

generator or hydro generator connected directly to the batteries. The XW Inverter/Charger Auxiliary Output can control a relay to disconnect the external charging source from the battery when the battery is in danger of being overcharged, or control a relay to turn on a diversion load.

• Activating a high-battery-voltage alarm such as a buzzer or light.• Activating a vent fan to disperse hydrogen from the battery compartment

when the batteries reach their gassing voltage.Low Batt Temp Activates the Auxiliary Output when the battery temperature falls below the Low Batt Temp setting for the trigger delay time. The Auxiliary Output turns off when the battery temperature rises above the Clear setting for the Clear Delay time. Battery temperature is measured with a battery temperature sensor. Do not use this setting if a battery temperature sensor is not installed. With this setting, the auxiliary output can turn on an indicator alarm if the batteries are too cold. A battery with frozen electrolyte will not accept a charge.High Batt Temp Activates the Auxiliary Output when the battery temperature rises above the Hi Batt Temp setting for the trigger delay time. The Auxiliary Output turns off when the battery temperature falls below the Clear setting for the

Configuration

Connections MenuThe Connections menu contains additional settings to allow the XW Inverter/Charger to function as part of a multi-unit networked system.Setting the connections for a Xanbus-enabled device provides a way of identifying non-network connections for Xanbus-enabled devices (see Figure 3-7) and enhancing networked power system management. When connections are set, devices of different types can detect that they share, for example, a common DC input source, or a common grid or generator source.In multi-unit networked systems, inverter/chargers can be stacked to produce increased charge current. To achieve this functionality, the devices must be configured to the same DC connection, such as House Battery Bank 1. The inverter/chargers will collaborate on battery charging by listening to other units on this shared DC connection.

For default settings, see “Connections Menu” on page B–6.

Important: When configuring multiple networked XW Inverter/Chargers with the System Control Panel, DC connections must be set to the same battery bank. If one of the units is set with a different DC connection, a system configuration fault (F66) occurs.

Although the XW Power System does support multiple XW Inverter/Chargers connected to multiple battery banks, such configurations cannot be set using the System Control Panel. A special configuration application provided by Xantrex is required. To configure such a system, contact your installer or Xantrex.

4 Troubleshooting

Chapter 4, “Troubleshooting”, contains information and procedures for solving possible problems with the XW Inverter/Charger.

Troubleshooting

Troubleshooting ReferenceThis section provides you with troubleshooting tips to identify and solve most problems that can occur with the XW Inverter/Charger.This chapter is divided into the following sections:1. “General Troubleshooting Guidelines” on page 4–22. “Inverter Applications” on page 4–33. “Inverter Troubleshooting” on page 4–54. “Battery Charger Troubleshooting” on page 4–85. “Faults and Warnings” on page 4–10

General Troubleshooting GuidelinesThis section will help you narrow down the source of any problem you may encounter. Please read the following troubleshooting steps:1. Check for a Warning or Fault message on the System Control Panel or a Fault

code on the inverter information panel. If a message is displayed, record it immediately.

2. As soon as possible, record on the form, “Information About Your System” on page WA–4, the conditions at the time the problem occurred. These details should include the following as well as any other information asked for on page page WA–4:• Loads the XW Inverter/Charger was running or attempting to run• Battery condition at the time of failure (voltage or battery level, for

example), if known• Recent sequence of events (for example, charging had just finished, utility

grid had failed but the inverter didn’t come on)• Any known unusual AC input factors such as low voltage or unstable

generator output• Extreme conditions which may have existed at the time (temperature or

moisture, for example).3. Attempt the solution indicated in Table 4-2 on page 4–11 or Table 4-5 on

page 4–18.4. If your inverter information panel or System Control Panel is not displaying a

Fault light, check the following list to make sure that the present state of the installation allows proper operation of the unit. See also “Inverter Troubleshooting” on page 4–5 and “Battery Charger Troubleshooting” on page 4–8.

p Is the inverter/charger located in a clean, dry, adequately ventilated place?

5. Contact Xantrex Customer Service for further assistance. Please be prepared to describe details of your system installation and provide the model and serial number of the unit. See page WA–1 for contact information.

Inverter ApplicationsThe XW Inverter/Charger performs differently depending on the AC loads connected to it. If you are having problems with any of your loads, read this section.

Resistive Loads

These are the loads that the inverter finds the simplest and most efficient to drive. Voltage and current are in phase, which means they are in step with one another. Resistive loads usually generate heat in order to accomplish their tasks. Toasters, coffee pots, and incandescent lights are typical resistive loads. It is usually impractical to run larger resistive loads—such as electric stoves and water heaters—from an inverter due to their high current requirements. Even though the inverter may be able to accommodate the load, the size of battery bank required would be impractical if the load is to be run for long periods.

Motor Loads

Induction motors (motors without brushes) require two to six times their running current on start up. The most demanding are those that start under load (for example, compressors and pumps). Of the capacitor start motors (typical in drill presses and band saws, for example), the largest you can expect to run is 1 hp. Universal motors are generally easier to start. Check that the Locked Rotor Amps (LRA) rating of the motor load does not exceed the maximum surge current rating of the inverter. Since motor characteristics vary, only testing will determine whether a specific load can be started and how long it can be run.If a motor fails to start within a few seconds or loses power after running for a time, it should be turned off. When the inverter attempts to start a load that is greater than it can handle, the inverter may shut down from an AC Overload fault.

Troubleshooting

Problem Loads

Very Small Loads

If the power consumed by a device is less than the threshold of the Search mode circuitry, and Search mode is enabled, the inverter will not run. Most likely the solution will be to disable the Search mode feature or lower the sense threshold. Refer to Xantrex Tech Note TN 003 (“Making Sense of Search Mode”) for more information.

Fluorescent Lights and Power Supplies

Some devices cannot be detected when scanned by Search mode circuitry. Small fluorescent lights are the most common example. Some computers and sophisticated electronics have power supplies that do not present a load until line voltage is available. When this occurs, each unit waits for the other to begin. To drive these loads, either a small companion load like a light bulb rated for more than the Search Watts setting must be used to bring the inverter out of Search mode, or the inverter may be programmed to remain on by disabling the Search feature. (See “Using Search Mode” on page 3–8.)

Clocks

You may notice that your clocks may not be accurate. Some of the clocks on your appliances may reset when the inverter/charger is in Search mode.

Searching

When the inverter is in Search mode, it may fail to start some loads even though the rated wattage on the load is more than the Search Watts setting. Apply an additional load (companion load) to make the inverter exit Search mode.

Inverter Troubleshooting

Inverter TroubleshootingTo determine the cause of an inverter error condition, refer to the troubleshooting solutions below to resolve the situation.

Problem Possible cause Solution

Unit will not come on (no LEDs are on) and the inverter information panel is blank or off.

Unit was turned off using On/Off button on front panel.

DC voltage on the inverter’s DC terminals is incorrect.

Turn the unit on again.

Check the battery voltage, fuses or breakers and DC cable connections to the inverter. If the DC voltage on the inverter’s DC terminals is correct, have unit serviced.

Unit comes on, but goes off quickly (several attempts made).

Excessive load on output.

Unit is in over-temperature protection and needs to cool down.

Remote Power Off signal is present.

Reduce loads.

Turn inverter off and allow the unit to cool and increase ventilation.

Release or reset the Remote Power Off switch.

No AC power output.INVERT LED is on, with no Fault/Warning LED.

Open AC output breakers or fuses and bad output wire connections.

Check the Load VAC status on the System Control Panel Meters screen and check AC voltage on the inverter AC Out terminal block.

If the Meters screen shows correct AC voltage but there is no AC voltage on the inverter AC Out terminal block, check for loose connections on the inverter terminal block. If connections are not loose, the inverter may need to be serviced.

If there is correct AC voltage on the Meters screen and on the inverter AC terminal block, check for open AC output breakers or fuses and bad output wire connections.

If AC voltage on the Meters screen or inverter AC terminal block is incorrect, have unit serviced.

No AC power output.INVERT LED is flashing.

AC load too small for Search Mode circuit to detect.

Reduce Search Watts setting, increase load above Search Watts setting, or turn off Search Mode on the Setup menu.

If the AC1 LED is on, check inverter output connections and voltage.

975-0240-01-01 4–5

Troubleshooting

Low AC power output or low surge power. INVERT LED is on.AC inductive loads are not running at full speed.

Insufficient DC current being provided to the inverter to operate the AC loads.

Check the battery voltage, fuses or breakers and cable connections.

Ensure the battery bank is sufficient (check for low DC voltage while running the load).

Ensure the cable length and size is correct (see Installation Guide for correct cable). Tie the battery cables together to reduce inductance.

Inverter turns on and then off or doesn’t turn on at all.

Search Watts setting is too low or high.

Potential problem loads for Search Mode:• Incandescent lights have a higher

starting wattage when the filament is cold than the continuous rating of the bulb.

• Fluorescent bulbs work the opposite of incandescent light bulbs. If the inverter is set to detect a 30-watt load and a 40-watt fluorescent is switched on, the inverter will not detect it, This is because the fluorescent tube is less than 30 watts until the gas in the tube ionizes.

• Other loads: Some appliances draw power even when turned off: TVs with instant-on circuits, microwaves with digital clocks, VCRs, and clocks.

If the search sensitivity is set higher than the combined loads, then an auxiliary load must be used to bring the inverter out of Search Mode before the appliances can be turned on.

If the sensitivity is set lower than the combination of the loads, the loads will remain on and excess battery drain will occur since the inverter won’t ever “idle.”

One solution is to turn the item off at the wall, use an extension cord with a rocker switch, a switch at the outlet, or an appropriate circuit breaker.


4–6 975-0240-01-01

Inverter Troubleshooting

In a grid-interactive mode, the unit is experiencing excessive anti-islanding faults. The utility grid is not dropping out, yet the unit is disconnecting from the grid.

The unit has two sets of AC limits: adjustable AC qualification limits (as set on the AC Settings menu), and non-adjustable anti-islanding limits which are required to have a 5-minute reconnect delay before returning to grid-interactive mode (Sell Mode or Grid Support).

While in Sell Mode and in Grid Support, these two sets of limits are both active. Whichever limits are set to more restrictive values (the narrower voltage and frequency windows) will trip first when the utility grid varies from normal values.

If the AC qualification limits are set outside the fast anti-islanding limits (see F27, F30, F37 and F40), the unit will experience less frequent disconnects from the utility, but when it does disconnect there will be a 5-minute delay (minimum) before re-entering a grid-interactive mode. During this 5-minute delay, all other modes of operation will be available, assuming the grid re-enters the user-set frequency and voltage limits (see “AC Settings” on page 3–16).

If the AC qualification limits are set inside the anti-islanding limits, then the unit will experience more frequent disconnects from the utility, but when it does disconnect there will not be a 5 minute delay before entering a grid-interactive mode, assuming the grid re-enters the user-set frequency and voltage qualification limits.

The impedance of the utility grid is too high for the power being sold to the grid. The utility grid impedance may be on the high end if the installation is too far from the utility sub station.

Adjust the AC1 voltage and frequency settings (see “AC Settings” on page 3–16). Raise the high voltage and frequency settings, and lower the low voltage and frequency settings.

Reduce the Max sell current until unit disconnecting.

1) Charger is disabled on the Setup menu.

2) Charger Block is enabled and the XW Inverter/Charger is inside of the Charger Block time window.

3) The XW Inverter/Charger is load shaving.

4) Charger is set for 2-stage charging and has completed a full charge cycle.

5) Battery voltage is low and AC voltage is high; in this case XW is a passive rectifier charger. For an active charger operation the following condition should be met: battery voltage > [0.16 × Vac input].

1) Enable the charger.

2) Disable Charger Block if you need to override this feature.

3) Check the Load Shave settings. If the load draw from the grid exceeds the Load Shave Amps setting, the charger will not operate.

4) No action required. The charger comes on when the battery reaches the Exit to Bulk setting. Otherwise use the “Force Chg” setting on the device setup menu to force a bulk or float charge.

5) No action required. Wait until AC input voltage becomes qualified, or allow the secondary charger to charge the battery.

AC1 or AC2 LED is flashing, but will not start charging(allow 40 seconds to synchronize).

AC voltage and frequency at the AC input terminal are within nominal range, but the inverter output is not yet synchronized to the AC source. The unit may be already synchronized to another AC source, or the unit is unable to synchronize to the AC input frequency.

The unit is operating normally. If the unit cannot synchronize to unstable generator input, service the generator.

Battery Charger Troubleshooting

Charger amperage drops off before full charging has finished (no Fault LED).

AC frequency at the AC input terminal may be out-of-tolerance (too high or low) or the AC voltage may be outside the Hi AC Volt or Lo AC Volt settings.

The charge settings are incorrectly configured for your battery type.

Ambient temperature may be high, causing unit to overheat and ramp down the charging.

Check the settings on the AC Settings menu. Check for the correct AC voltage or frequency at the AC input terminal. If the AC source is a generator, adjust the AC voltage or frequency accordingly.Increase the difference between the Hi AC Volt (AC1) and Lo AC Volt (AC1) settings to allow synchronization.

Select the correct battery type or configure a Custom Battery type.

Cool the unit down or check for anything preventing air flow around the unit.

Charger stops before full charging (or equalization) has finished.Fault LED flashes and AC output drops momentarily.

Cold temperature around batteries with battery temperature sensor (BTS) installed may be causing unit to reach High Batt Cut Out setting.

Disconnect BTS during charging or increase High Batt Cut Out setting.

Charger output is low. Loose or corroded battery connections.

Loose AC input connections.

Worn-out batteries.

Battery cables too small or too long.

Check and clean all connections.

Check and tighten AC wiring connections.

Replace batteries.

Refer to cable and battery recommendations in Installation Guide.

Batteries being charged above the Bulk/Float setting.

If BTS is installed, it may be in a cold area or have fallen off the batteries.

Another DC charging source may be on the batteries.

Inspect the BTS. Reduce the Batt Temp Comp setting on the Custom Battery Settings menu.

NOTE: To bring batteries that are cold to the correct state of charge may require charging at a higher voltage. This may be normal BTS operation. Unplug the BTS and determine if your voltage returns to the bulk/float voltage.

Troubleshooting

Fault Types

There are three types of fault messages: automatic faults, manual faults, and escalating automatic faults. Table 4-3 describes how they differ in their behavior and how you can respond to them when they appear on the XW System Control Panel.

Inverter Operation After Faults

XW Inverter/Charger operation changes when a fault occurs. How the operation changes depends on the operating state of the unit when the fault occurred—inverting, charging, grid or generator support, AC bypass, and so on—and on which fault has occurred.

Table 4-3 Fault Types and Behaviors

Fault type Behavior

Automatic faults Clear automatically if the fault condition that generated the message goes away. You can also acknowledge automatic faults without waiting for them to clear automatically.

Manual faults Require you to clear them by:• selecting Clear Faults on the Main XW Inverter/Charger

menu or on the menu for the Xanbus-enabled device that generated the fault (if the fault condition still exists, the fault message reappears)

• correcting the condition that caused the fault.Escalating automatic faults

Clear automatically if the fault condition goes away, just like an automatic fault.However, if an escalating automatic fault occurs several times within a defined time period, the escalating automatic fault becomes a manual fault, requiring user intervention. For example, if an AC Overload fault occurs three times in five minutes, it will no longer clear itself and become a manual fault. Then you must identify the problem, correct the fault condition, and clear the fault.

Table 4-4 Inverter Operation After Faults

Faults State when Faults Occur Action After Faults

F1, F2: AC Output Inverting Unit stops inverting and waits for nominal AC output voltage level, or a manual clear from user.

F3 to F10: AC1 Input Voltage and Frequency

AC1 input is the preferred source and qualified.

Unit begins inverting (if inverter is enabled) or disengages AC1 and waits for nominal AC1 input (if inverting is disabled).

F11 to F16: AC2 Input Voltage and Frequency.

AC2 input is the preferred source and qualified.

Unit begins inverting (if inverter is enabled) or disengages AC2 and waits for nominal AC2 input (if inverting is disabled).

Faults and Warnings

F17 to F22: Relay Welded

Inverting Unit stops inverting and waits for user to clear fault.

F23 to F40: Anti-Islanding

Grid Support (Peak Load Shaving or Selling)

Moves to AC bypass and waits for nominal grid conditions to return for a minimum of five minutes.

F41, F42: Aux power supply voltage

Unit shuts down and waits for nominal AC output voltage level, or a manual clear from user.

F44: Battery Over TempF45: Capacitor Over Temp

Any state. If inverting, the unit shuts down and waits for the temperature to return to nominal value. If in any of the AC-interactive states (charging, peak load shaving, sell, gen support), the unit goes into AC bypass mode until the temperature returns to the nominal value. If the unit is not in AC bypass, it shuts down until the temperature returns to nominal value. After these faults clear, the unit returns to its previous operating state.

F47 to F49: DC Voltage

Unit is inverting or has qualified AC input and is preparing to charge.

If inverting, the unit shuts down and waits for nominal voltage. If operating with a qualified AC source, the unit charges if charging is enabled, or remains in AC bypass if charging is disabled.

F63 to F65: AC Overload

Inverting or Grid Support Unit stops inverting and waits to qualify AC. Unit waits for user to manually clear fault.

XW Inverter/Charger Overload Capability

Loads presented to the inverter are seldom constant. Typically, large loads are operated for only short periods of time. In order to provide the maximum utility, Xantrex inverters are allowed to operate at power levels that exceed their continuous power ratings. This graph shows how loads that are larger than the inverter can sustain continuously can be operated for useful periods of time.The length of time that the inverter can operate at high power is limited by temperature. When large loads are run, the inverter’s temperature increases. At the point where more heat is created in the inverter than can be dissipated, its ability to operate becomes time limited.
